Abstract

In this paper, we present a new multidimensional access method, called hana tree, which can provide an efficient and robust way for dynamic modifications and interactive queries to spatial database. We designed a new multidimensional binary encoding scheme, hana code, for representing points and page regions in hana tree. When a new spatial data is inserted in uncovered data space, the page region of the existing node is expanded to include it instead of creating a new one. These properties allow the decrease in the total number of nodes and the reduction in the number of nodes accessed during search, thus improving the overall performance in storage space utilization and various operations Also, we shall describe our experimental results where hana tree is compared to other point access methods to show the superiority of hana tree.
